Abstract (en)

[origin: EP0563769A1] A description is given of a monitoring device for frozen foods, with the aid of which overshooting of an additional storage temperature is irreversibly indicated. A flat plastic bag with transparent walls is connected to the frozen goods in a thermally conductive fashion, and a eutectic medium having a liquid/solid phase transition in the range from 0 DEG C to -50 DEG C is introduced into said bag together with a magnetic dispersion consisting of finely disperse magnetic pigments. Bonded on the bag is a magnetic strip which contains a magnetically recorded pattern and which remains connected to the bag until the monitoring device with the frozen goods is cooled below the limiting temperature. The magnetic strip is then removed. Upon overshooting of the permissible limiting temperature, the optically or magnetically readable structure generated by the magnetic strip is cancelled in the monitoring bag, so that it is easy to monitor the frozen food. The invention permits numerous varying possibilities by the combination of a plurality of mounted magnetic strips.
